Method and device for transmitting electrical power and signals between a wall and a leaf pivotable relative thereto

Abstract

A method for transmitting electrical power and first and second signals between a wall and a leaf pivotable relative to the wall. The method includes providing a leaf comprising an electric consumer and an electrical signal transmitter, providing a control and evaluation unit on a wall, providing a single power transmitting device, providing a first optocoupler, and providing a second optocoupler. The electrical actuating power and the electrical operating power are transmitted from the wall to the leaf in a galvanically isolated manner via the single power transmitting device. The first signals are transmitted from the leaf to the wall via the first optocoupler so as to regulate the electrical power supplied on the wall according to an actuating and operating power demand. The second signals are transmitted bidirectionally between the control and evaluation unit on the wall and the electric signal transmitter on the leaf via the second optocoupler.
